000 WTPA32 PHFO 060236 TCPCP2 BULLETIN Post-Tropical Cyclone Flossie Advisory Number 35 NWS Central Pacific Hurricane Center Honolulu HI EP072019 500 PM HST Mon Aug 05 2019 ...FLOSSIE DEGENERATES TO A REMNANT LOW AS IT PASSES NEAR HAWAII... SUMMARY OF 500 PM HST...0300 UTC...INFORMATION ---------------------------------------------- LOCATION...20.8N 154.6W ABOUT 85 MI...135 KM NNE OF HILO HAWAII ABOUT 90 MI...145 KM E OF HANA HAWAII MAXIMUM SUSTAINED WINDS...35 MPH...55 KM/H PRESENT MOVEMENT...WNW OR 300 DEGREES AT 12 MPH...19 KM/H MINIMUM CENTRAL PRESSURE...1009 MB...29.80 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 500 PM HST (0300 UTC), the center of Post-Tropical Cyclone Flossie was located near latitude 20.8 North, longitude 154.6 West. The post-tropical cyclone is moving toward the west-northwest near 12 mph (19 km/h). A gradual turn toward the north-northwest is expected until dissipation on Wednesday. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Flossie is expected to gradually degenerate over the next day or so and dissipate by Wednesday. The estimated minimum central pressure is 1009 mb (29.80 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Flossie will continue to affect the main Hawaiian Islands into Tuesday, producing hazardous surf conditions along east facing shores. RAINFALL: Moisture associated with Flossie will spread over portions of the main Hawaiian Islands during the next couple of days, bringing the potential for heavy rainfall. Total rainfall amounts of 1 to 4 inches are possible. Please consult products from the National Weather Service in Honolulu for more information. NEXT ADVISORY ------------- This is the last public advisory issued by the Central Pacific Hurricane Center on Flossie. Additional information on the post-tropical low can be found in high seas forecasts issued by the National Weather Service under AWIPS head HFOHSFNP, WMO header FZPN40 PHFO, and on the web at https://www.weather.gov/hfo/HSFNP $$ Forecaster Wroe

000 WTPA42 PHFO 060237 TCDCP2 Post-Tropical Cyclone Flossie Discussion Number 35 NWS Central Pacific Hurricane Center Honolulu HI EP072019 500 PM HST Mon Aug 05 2019 Vigorous deep convection has been persistent through much of the day to the northeast of the cloud system center, which has become significantly elongated and poorly defined by several outflow boundaries. Recent analyses of satellite cloud drift winds suggest that the highly elongated cloud system center is lacking westerly winds that define a closed area of low pressure, and subjective Dvorak current intensity estimates were 25 kt from HFO and SAB, while JTWC deemed the system too weak to classify. Given these inputs and the presence of continued vertical wind shear of more than 30 kt, Flossie will be designated a post-tropical remnant low. The intensity will remain 30 kt, since an ASCAT-C pass earlier in the day detected winds this strong within the deep convection. While the cloud system center could arguably be a trough, a mean center location gives an initial motion of 300/10 kt. Under relentless vertical wind shear, the remnant low will continue to degenerate as it passes near the main Hawaiian Islands. The westerly vertical wind shear will be maintained by a deep upper-level trough parked northwest of the Hawaiian Islands. This upper trough is also eroding the low- to mid-level ridge that is steering Flossie. As a result, the remnant low will gradually turn toward the northwest tonight, then shift toward the north-northwest until dissipation on Wednesday. The track forecast was nudged to the right from the prior advisory and is near TVCN. All guidance shows weakening or little change in intensity until dissipation. This is the last advisory on Flossie. Additional information on this system can be found in the High Seas Forecasts issued by the National Weather Service in Honolulu under AWIPS header HFOHSFNP and WMO header FZPN40 PHFO. Interests in the main Hawaiian Islands should refer to products issued by the National Weather Service in Honolulu for information on flooding and surf impacts.
